In the Solo Leveling world, Guilds play a crucial role in organizing and managing hunters, who are individuals with special abilities who undertake missions to protect humanity from monsters and dungeons. Guilds provide resources, support, and opportunities for hunters to grow their strength and skills, as well as offer a sense of community and camaraderie among members. Guilds also compete against each other for dominance and influence in the hunter community, making them a key aspect of the world's power dynamics.
